4 Claims. (01. 98- 115) My invention relates to ventilators of a typeused to carry away cooking odors, smoke, heat and grease-laden fumesfrom kitchensgas ranges and stoves used for similar purposes.

In this connection, one of the principal objects of the invention is'theprovision of a ventilator of the type referred to and adaptable to anykitchen of the home or elsewhere wherever a flue and electrical serviceare available, and which may be installed at a minimum of cost.

Another object of the invention is the novel and simple construction ofthe .ventilator and wherein the exhausting unit. and the smoke deflectorare capable of easy removal for thepurl5 pose of cleaning,,inspection orreplacement.

Another important object of the invention is the construction andarrangement of the smoke deflector, said deflector permitting thesuction of air to draw the smoke and fumes over the entire '20 area ofthe inside of the hood.

the invention will beclearly understood from a perusal of the followingdetailed description, taken in connection with the accompanying drawing,and wherein:

Figure 1 represents a perspective view in part of a gas cooking rangeand a ventilator and illustrating an embodiment of the invention, theventilator hood being partly broken away,

Figure 2 is a vertical transverse sectional view through the hood inFigure 1 showing in detail the various parts of the. ventilator,

Figure 3 represents a top plan view of Figure 2 of the smoke deflectorand exhaust unit, the hood not shown,

Figure 4 represents a. vertical sectional detail view of Figure 3, theview being taken on the line 4-'- '-4 thereof, and showing the exhaustunit, and

Figure 5 is a. front elevational view of the exhaust unit housing 'coverplate.

Referring moreyin detail. to the drawing, like parts being designated bylike characters, 1 in'-' dicates a gas or similar cooking range ofmodern type, although the ventilator is adaptable .to any 45 type ofcooking stove where a flue outlet and electrical service-are available.The ventilator consist's of a backboard or support 2 and a hood 3, theseparts being adaptable to installation in kitchens-of new or olddwellings and apartments.-

50 and being secured to the kitchen wall by the dwelling.

Secured to the board 2 is the hood 3 with the 55 lateral panels 5, theseparts being positioned above With the foregoing and other objects inview provided with the burners so as to catchanddirect the smoke andfumes into the exhaust unit.

As illustrated more clearly in Figure 2 theexhaust unit consists of apowerful centrifugal blower 6,.not merely an electric fan, so that theblower is positive in action and has a suction equal to that ,of a.large exhaust fan. This blower is quiet in action andis operated by anelectric motor I through the motor shaft 8 upon which the blower ismounted.

The motor I and blower Gare enclosed in a housing consisting of a bottomwall or support I 2, secured by screws to the backboard or support 2, arear wall l0, side walls Illa and a removable cover plate I I. Thecover. plate is shown by itself in Figure,5.

The horizontal partition walls l2, l3, and vertical wall 13a and thecurved por'tion l3b thus complete the closure for the blower and enablethe air suction, created by the blower, and as indicated by the arrows,to flow into this closure through the opening l4 and exhaust into theflue pipe 4 through the vent l5. As shown in Figure 3, the side wallsIna are bent at rightangles to provide a flange lllb for fastening thesewalls to the hood 3,

A conduit pipe I! with light globe I8 and pull cord l9 provide lightingfacilities and a pull cord 20 starts and stops the motor I. A bracket 2|supports the conduit on the wall III. The cover plate II includes arounded notch 23 to receive the conduit pipe l1 and the cover plate isalso apertures 24 which fasterr over the stud bolts 25, welded to theside walls Ila, and the wing nuts 26 hold the cover plate in position.Consequently the cover plate may be easily removed by taking off thewing nuts and the blower and adjacent parts cleaned, inspected, or partsreplaced.

In addition to the foregoing I provide a smoke deflector with upwardlyslanting walls 21 and 28, the'upper edges of which extend on a linemidway across the opening l4 in the cover plate Il,'leaving a narrowopening for smoke and fumes to pass over its edges to the blower. Asshown by the arrows, Figure 2,'the smoke and grease-laden fumes are thusdeflected upwardly. The smoke deflector is an important'feature of myinvention and provides a means whereby the suction from the blower isspread over the entire area of the'inside of the hood. The smokedeflector is secured to the bottom wall I! by stud bolts and wing nutsill, making it easily removable for cleaning, inspection or replacementof parts.

While I have shown and described a practical working embodiment of myinvention,- it is apparent that parts'thereof may be modified, alteredand chang without departing from the intent of the invention, and withinthe scope and 5 meaning of the appended claims.

WhatIclaim as new is: 1. A ventilator of the class described and adaptedto be used with a hood, said ventilator comprising'a housing having arearwardly projecting support, a centrifugal blower for creating airsuction, and electric motor-mounted on the said projecting support foroperating said blower,

walls, and a rear partition wall, said partition wall separating themotor and blower, a removable covr plate for the housing, said platehaving an opening for inlet of smoke and fumes, and said top wall havingan opening for exhaust of said fumes and smoke, and including a smokedeflecting ,means projecting outwardly and upwardly from the'lower partof the said housing.

. 2. A ventilator of the class described in combination with a hood, thesaid ventilator comprising '25 a housing having a rearwardly projectingsupport, a centrifugal blower in the housing, an electric motor foroperating said blower mounted on the said support, a smoke deflectingmeans comprising an apron removably secured to the lower 30 portion ofsaid housing and directed outwardly and upwardly, the upper edges ofsaid apron being disposed below and inside the surface of the said hoodto be used with the ventilator and providing a space for entrance ofsmoke and the like to be suction, an electric motor mounted on the saidprojecting support for operating said blower, the blower being inclosedby the housing, said housing including a bottom wall,'a top wall,-sidewalls, the blower being inclosed by the housing, said housing includinga bottom wall, a top wall, side and a rear partition wall, saidpartition wall separating the motor and blower, a removable cover platefor the housing, said plate having an opening for, inlet of smoke andfumes, and said top wall having an opening for exhaust of said fumes andsmoke, and a smoke deflecting means comprising an apron removablysecured to the lower portion of said housing and directed outwardly andupwardly therefrom within the area of the hood, the upper edges of saidapron being disposedbelow the inside surface of said hood and provi ng aspace for entrance of smoke and the like to be drawn into said openingof said cover plate.

4. A ventilator of the class described and as claimed in claim 1, saidhousing including also a curved wall and the said curved wall beingaccessible by removing the said removable cover.
